Answer:
6.75 or 6 3/4 gallons
Step-by-step explanation:
First we can add the whole numbers together: 3 + 2 = 5
Now, we need to add 7/8 + 7/8, this is the same as multiplying 7/8 times 2.
2= 2/1, and we multiply across when multiplying fractions, so it would look like:
7/8 × 2/1=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
7×2= 14
8×1= 8
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 14 and 8 using
GCF(14,8) = 2
14÷2 = 7
8÷2= 4
The fraction
7/4
is the same as
7÷4= 1.75
Finally we just add 1,75 + 5 = 6.75 or 6 3/4 since 3/4= 0.75
